Dear Rajeev,
To install R-connect to my laptop thru N-2112 (with CA-42 cable), I installed Nokia Connectivity Cable Drivers from the www.nokia.com Support web pages. I then followed your refered link & downloaded RConnect s/w from reliance website. On installing the RConnect s/w, it again asks for installing cable driver (which means that it does not recognise already installed cable driver). If I say yes, it automatically installs the DKU-5 drivers. Subsequently, it asks me to connect the phone. On connection, the laptop recognises the new hardware & installs the modem. Even though the system pops up that modem is installed (which I also checked in control panel > phones & modems), the RConnect s/w does not proceed further. It does not make the 'Next' tab active for me to complete the installation.
I checked out with few friends & came to know tht it is a frequent problem.
Any ideas on this?
